The lab uncovers welding and joining phenomena through mathematical formulas and simulation.
AboutAbout the lab
Capturing welding and joining phenomena with equations and computation
The Mathematical Analysis Field studies welding and joining technology for ships, which are huge structures built from metal.
The lab mathematically models various phenomena in which welding heat sources, welding materials, and mechanical loads combine, and investigates them through numerical simulation.
This technology can be applied to all kinds of structures, not only ships, and research on modeling and simulation is expected to lead to the evaluation of joining technologies for future transport equipment.
To evaluate the safety of structures, the lab also addresses the thermodynamic phenomena of solid-state joining and additive manufacturing through research and development of numerical analysis software and measurement methods.
Key terms
- Numerical simulation
- A method of expressing a phenomenon in mathematical equations and calculating it on a computer to reproduce its behavior
- Solid-state joining
- A joining method that connects materials such as metals in the solid state, without melting them
- Additive manufacturing
- A processing method that builds three-dimensional shapes by stacking material in layers
ResearchResearch themes
